Review on Trido Covert Acoustic Tube Two Wire Earpiece Headset Mic PTT | Motorola Radio XPR3500 XPR3000 XPR3300 XPR3300e XPR3500e Walkie Talkie by Mike Goodwin

I ordered 5 of these for work. I put them on several different radios (Motorola XPR3500e) and NONE of them broadcast. There was a click in the speaker when the microphone was pressed, but the voice transmission did not go through on ONE. The company then exchanged 11 emails with me before telling me they had to be returned for a refund. I suspect a production error as none of the ones I ordered fitted and they all had the same problem. Let the buyer be alert.
